This invention relates to moth exterminators. "a One of the objects of the invention lies in the provision of a ball type moth extermina- 5 tor, the same comprising a base portion containing a solidified chemical and a detachable apertured cover and an electric heating element disposed within the the container in a manner to liquefy the chemical, whereupon a vapor fatal to moths escapes from the apertures.

Another object lies in the provision of a moth exterminator of a ball type, the same containin a solidified chemical adapted to be liquefied y a heating element, the escaping vapors being fatal to moths, said container being further so fashioned as to automatically seat itself in an upright position, ir-

respggtive of the position in which same la p Other objects will appear in the following,

' specification taken in connection with the annexed drawing, in which Fig. 1 is a plan view of my ball shaped Fig. 2 is an elevational view thereof;

- Fig. 3 is a cross-sectional view on line 3-3 of Fig. 1; i

gFi 4 isa cross-sectional view taken on .9 the li iie 44 .of Fig. 3.

Before referring specificall to the drawing, it might be stated that t e method em-' ployed in-the resent application for the extermination o insects, including especially moths,'has been described and claimed in my copending a plication, Ser. No. 533,640, filed A ril 29, 19 1.

he present a plication is directed to a specially form ball sha container, by the operator and placed in operative position in closets, beneath furniture" and generally in more remote positions than canordinarily beobtained by moth exterminato'rs having a more conventional shape. 7

Referring specifically to the drawing; it is found that the container is rounded or s aped in the form of a ball. The base portion of the container, designated 10, is adapted toreceive a quantity of solidified chemical 11,

- ical 11 is foun details of which have been described in detail in my above referred to pending a plication. This chemical, whenin a coo state, becomes a solid; however, when liquefied by the presence of heat, the chemical gives off a vapor which is fatal to insects and especially moths.

The up r portion of the ball has been designate 12, the same being rounded in form and 'detachably connected to the base 30 by means of the co-operating detachable connecting means 13 on the cover and 14 on the base respectivel 8 Obviousl t is connection between the cover and ass .of the ball mi ht be accom- F plished in numerous ways an this manner of connection has merely been shown for the purpose of showing that the cover may be detached from the base by simple manual operation which is necessary for re lenishing the base with a new chemical w en the OH inal supply has been exhausted,

he cover member is apertured as at 15 in a manner to permit escape of the vapors".

Means for-1i uefying the scilidified chemin the electric element of a resistance type the same being described generally as 16. it is quite obvious that this resistance or heatin element might be made in various forms, it ing merely essential that 9 same be disposed within the container in such position that the heat therefrom will liquefy the solidified chemical 11.

It may be expained that no vapor escapes from the chemical 11 when in the solidified form. g

Current is supplied to the electric connection through the electric cord 17, this cord operating not only to supply electric current to the heating element, but also asa suspension and supporting means for the container as a whole. Conventional insulating means for the cord is shown at 1 8.

With respect to the operation of the device, it is apparent that same may be transported by the operator by merely grasping the cord 17. This provides convenient trans- E ortatio'n and supporting means for the ball.

he cord 17 normally is of sufficient length am e ball may be placed or rolled to a A rolled to a position beneath the furniture,

whereupon the ball will automatically seat itself in an upright position. By such fashioning of the ball, the same may be disposed in remote laces where the placement thereof may be di cult, or further it might berolled into such remote positions that might otherwise not be reached.

Assuming that the ball has'reached the desired lace and has assumed an upright position, t e operator then merely connects plug 20 in the conventional current socket, whereupon the electric heating element 16 becomes heated and ii uefies the solidified chemical 11. The liqudhcation of the chemical 11 results in the escape of vapors through the apertures 15, which vapors when coming in contact with the fabric material, irrespective of its character, forms a coating thereon, which absolutely exterminates moths, larvae or $11811 applicants device has served its purpose of killing the moths, obviously it is simple to break the electric current by pull- 1 ing out the plug 20 and thereafter either placing or rolling the ball into adifierent place tion.

at I claim is: 1. A portable moth exterminator comprising a container having a base portion adapted to contain a solidified moth-exterminating adapted to protect the chemical from displacement and accidental disturbances, said cover member being provided with restricted apertures for discharging vapors from said container, an electrical heating element mounted within and surrounded by said cover chemical, and a cover member for said base for said base adapted to protect the chemical from displacement and accidental disturbances, said cover member being provided with a restricted opening for discharging vapors from said container, an electrical heating element mounted wholly within and surrounded by said cover member so as to be protected thereby, said heating element being located, when the cover is closed, adjacent to but out of contact with the exposed surface of said chemical, whereby the chemical is heated and converted from a solid to a vapor state, and a detachable connection between the base portion and the cover member at a substantially intermediate point so that the base member and cover member form complementary shells of approximately equal volumes, said detachable connection permitting ready removal of the cover to permit the insertion of the solidified chemical within the base.

In testimony whereof I have hereunto affixed my signature.

member so as to be protected thereby, said heating element being located, when the cover is closed, adjacent to said chemical whereby the chemical is heated and converted from a solid to a liquid state and a detachable connection between the base portion and the cover member at a substantially intermediate point, said detachable connection permitting ready removal of the cover member to permit the insertion of the solidified chemical within the base.

2. A portable moth exterminator comprising a container having a base portion adapted to contain a solidified moth-exterminating chemical, and a dome-shaped cover member
